adjustment of the pressure'on the rolls eiIected V by the screw. Features and details will appear from the spciilcation and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing as follows:

Fig. 1 shows a detached screw with its operating handle thereon.

Fig. 2 a cr'oss section of a wringer on the line 2-2 in Fig. 4.

Fig. Ail a section on the line 3 3 in Fig. l.

Fig.4 an elevation of a wringer with the screw in place. y

i marks a wrlnger frame, 2 the top of the wringer frame, l and tithe wringer rolls, l the shafts of the wringer rolls, t a bearing for ythe upper shaft, I a plate spring operating on the bearing 6, 8 a pressure screw, il'a head on the end of the pressure screw engaging the spring, IIJ a clip locking the pressure screw in place on the spring, il a nut secured in the top of the wringer frame in which the screw operates. 'I'hese parts are or may be, sotar as described, of common construction.

The screw has an extension ila on which is arranged a handle I2. 'Ihis handle is preferably elongated and may be hollow, preferably with a surrounding skirt I3. It has a cross wall il which is provided with an opening il, preferably closed at the top, which opening is adapted to slidingly receive the upper end of the screw. The vhandle has'an axially extending slot Il through it forming an opening to the front and rearA of the handle exposing the upper end of the screw.

A pin i1 extends through a cross yopening in the the adjustment of the screw as eecting the..

pressure on the rolls. The pin Il may have a mark I9 acrosseach face and the handle is pro- (cl. es-zsz) vided with an index ordinarily marked low, med. and high, having the scale marks 2l which are-adapted to register with the line Il to give .amore definite reading oi the adjustment.

By making the handle elongated it is ordinar- I ily adjusted'to a position lengthwise of the top bringing the slot directly into view of the operator. This structure makes a very simple, rugged and eiective structure for operating the screw and for indicating the adjustment.

What I claim as new is:

1. A pressure adjusting means for adjusting pressure from a wringer frame to resilient pressure means comprising a screw; a nut in which the screw operates; and a handle for the screw.4 said handle being rotatively locked and axially movable relatively to the screw, and having an opening in the side thereof disclosing the adjusted position of the screw.

2. A pressure adjusting means for adjusting pressure from a wringer frame to resilient pressure means comprising a screw; a nut in which the screw operates; a handle having an axial opening slidingly receiving the screw and an axially extending slot in the tace of the handle ,35 leading to the opening; and avpin in the screw extending into the slot.

3. A pressure adjusting means for adjusting pressure from a wringer frame to resilient pres# sure means comprising ascrew; a nut in which the screw operates; a handle having an axial opening for slidingly receiving the screwJ and an axially extending slot extending through the handle from front to rear ;-.'and a pin extending through the screw and projecting into the front and rear slots.

4. A pressure adjusting means for adjusting pressur'efrom a wringer frame to resilient pres. sure means comprising a screw: a nut in which the screw operates; a handle having anl axial opening for slidingly receiving the screw, and

an axially extending slot in the face oi' the handle leading to the opening; a pin in the-screw extending into the slot; and an index on the handle with which the pin is adapted to register.
